A few years ago, the editors of Guitar World magazine compiled what we feel is the ultimate guide to the 100 Greatest Guitar Solos of All Time.

The list, which has been quoted by countless artists, websites and publications around the world, starts with Richie Sambora's work on Bon Jovi's “Wanted Dead or Alive” (100) and builds to a truly epic finish with Jimmy Page's solo on "Stairway to Heaven" (01).

In June, we kicked off a summer blockbuster of our own — a no-holds-barred six-string shootout. We pitted Guitar World's top 64 guitar solos against each other in an NCAA-style, 64-team single-elimination tournament. Every day, we asked you to cast your vote in a different guitar-solo matchup as dictated by the 64-team-style bracket. Now Round 1 has come and gone, leaving us with 32 guitar solo and 16 (sweet) matchups.

You can vote only once per matchup, and the voting ends as soon as the next matchup is posted (Basically, that's one poll per day).

In some cases, genre will clash against genre; a thrash solo might compete against a Southern rock solo, for instance. But let's get real: They're all guitar solos, played on guitars, by guitarists, most of them in some subset of the umbrella genre of rock. When choosing, it might have to come down to, "Which solo is more original and creative? Which is more iconic? or Which one kicks a larger, more impressive assemblage of asses?"

Today, it's Dimebag Darrell's solo on Pantera's "Floods" (19) against Zakk Wylde's solo on Ozzy Osbourne's "No More Tears" (51). "Floods" moved into to Round 2 by knocking off Eddie Van Halen's "Hot for Teacher" in the first round. Meanwhile, "No More Tears" crushed "Layla" to make its way into the second round.
